Accessory Drive Belt Guide for the 1963-1964 Studebaker 8E7 Truck
Keep your Studebaker's V8 running cool and charging right with a modern, reliable V-belt.
- A failing belt gives warnings like squealing or visible cracks; replace it immediately to avoid being stranded.
- Modern aftermarket brands like Gates, Dayco, and Continental offer superior materials and reliability compared to any remaining original stock.
- A broken belt will cause the engine to overheat and the battery to stop charging, making the truck undrivable.
- Replacing the V-belt is a simple, low-cost DIY job that most owners can do in under 30 minutes with basic tools.
Is Your Studebaker's Belt Trying to Tell You Something?
A failing V-belt on a classic truck like the 8E7 provides clear warning signs. Because it runs critical components, you should address these symptoms immediately to avoid being stranded or causing expensive engine damage. Pay attention to these signals:
- Squealing Noises: The most common symptom is a high-pitched squeal, especially when you start the engine or accelerate. This is caused by the belt slipping on the pulleys due to wear, incorrect tension, or contamination from oil or coolant.
- Visible Wear and Damage: A quick visual inspection can tell you a lot. Look for cracks, fraying, missing chunks, or a shiny, glazed surface on the sides of the belt. Old rubber becomes brittle and is a sure sign that replacement is needed.
- Charging System Issues: If the belt is slipping, it cannot turn the generator fast enough to charge the battery. You might notice the "GEN" light on your dashboard glowing, or your headlights may appear dim at idle.
- Engine Overheating: If the belt breaks or is slipping badly, it will not turn the water pump. This will cause the engine temperature to rise quickly, which can lead to severe engine damage if not addressed immediately.
Choosing the Right Aftermarket Belt: Quality and Brands
For a vintage truck, the choice between "OEM" and aftermarket is simple. Original Studebaker-branded belts are no longer made. While you might find a "New Old Stock" (NOS) belt online, a 60-year-old piece of rubber is not a reliable part for a working truck. Rubber degrades over time, regardless of use, becoming brittle and prone to failure. Modern aftermarket belts from reputable brands are made with superior rubber compounds that are far more resistant to heat, oil, and cracking than the originals.
For your 1963-64 Studebaker 8E7, brands like Gates, Dayco, and Continental are all excellent, high-quality choices. All three are known for making durable belts that meet or exceed original specifications. There is little practical difference in quality between them for this type of V-belt application, so choosing any of these brands will provide a reliable part.
Pro Tip: Check Your Length
The most common ordering mistake is getting the wrong size belt. Studebaker may have used different belt lengths depending on accessories like air conditioning. If you are unsure which belt to order, the most reliable method is to measure the outside circumference of your old belt before throwing it away.

Frequently Asked Questions (FAQ)
Is it hard to replace the accessory drive belt myself?
No, this is a very easy job for a DIYer on a 1960s Studebaker. The process involves loosening the mounting bolts on the generator, pivoting it to create slack, swapping the old belt for the new one, and then applying tension to the belt while tightening the generator bolts. It requires only basic hand tools and can usually be done in under 30 minutes.
How do I know if the new belt has the right tension?
Proper tension is critical. If it's too tight, it can damage the bearings in your generator or water pump. If it's too loose, it will slip and squeal. A good rule of thumb is that at the longest point between pulleys, you should be able to twist the belt about 90 degrees (a quarter turn) with your fingers.
Why is my new belt squealing?
The most common reason for a new belt to squeal is incorrect tension; it's probably too loose. It could also be caused by oil or coolant residue on the pulleys. Always clean the pulleys before installing a new belt. Worn or misaligned pulleys can also cause noise.
Are there any recalls for the accessory drive belt on my truck?
No. There are no recalls or Technical Service Bulletins (TSBs) for this part on a 1963-1964 Studebaker. The vehicle predates the modern NHTSA recall system, and any issues you encounter will be due to normal wear and tear on this simple mechanical system.
Technical Specifications
The 1963-1964 Studebaker 8E7 uses a V-belt system. The specific length and width of the belt depend on the engine (4.2L or 4.7L V8) and factory-installed accessories like air conditioning. Belts are typically made of modern EPDM rubber compounds for heat and oil resistance.
